John, Mike, list
1] John - thanks for the clarification of your slide #9, Cognitive Learning.
I mistook the three slides showing brain activity to refer to the Peircean categories - and was puzzled, since Feeling/Firstness does not, according to Peirce, require a brain. As he said, 'protoplasm' feels...and this is a non-conscious, i.e., non-mental experience. My error regarding your slides.
2] With regard to your slide #4 of machine learning - I've got two points.
I can see, actually, that the triangle is an accurate image in ML, - and comment that such linearity is a key problem in ML. That's why I prefer the triadic spokes or Y shape provided by Peirce for the semiosic Sign because it rejects the linear force - which can be quite overpowering like an avalanche - and enables mediation...which is never linear. Machines have trouble with mediation!
I don't see, as does Mike, that this is related to the categories, but could be wrong, and would also appreciate your clarification.
3] At any rate, I've suggested years ago, that the semiosic triadic act is a function: f{x]=y, where 'f' is mediation. Your slide 5 shows this quite well, AND, in addition, shows the vital nature of this mediation or 'hidden layer'. What is interesting is that your hidden layer[s] is complex/multiple. My view is that this is why Thirdness has three modes: 3-3, 3-2, 3-1 - to provide complexity of organization/transformation of input to output.
My paper, presented in Dubois' conference on Computing Anticipatory Systems, examines the complex actions of this mediation within the three modes of Thirdness and as a function...and even, puts these actions on a different spatial and temporal zone than the actions of 1ns,2ns.
Note - I've tried to attach my paper, The Sign as a WFF/well-formed formula, but this new computer doesn't have all my papers and I'm an idiot dealing with computers.

Hi John, List,
I appreciate you keep trying to get us back on target with your comments.
I think the reference Edwina brought forward is the best I've seen so
far for these arguments with respect to the neurophysiology of Thirdness
mediation. Do you agree?
I think I understand your points on slides 7-11 of your short version
http://jfsowa.com/talks/vrshort.pdf.
However, what stopped me in this deck is slide #4. Framing the ML
methods into the triadic triangle format you prefer (as do I) seems to
imply you are relating these ML methods to the universal categories. Is
that your intent? If so, I'd love to hear the rationale behind that.
Best, Mike
